Explanation:
< File1 is deduplicated after the deduplication job runs. - YES
File3 is deduplicated after the deduplication job runs. - NO
File4 is deduplicated after the deduplication job runs. - NO
The Administering Windows Server Hybrid Core Infrastructure materials explain that Data Deduplication operates per-volume and only processes files on volumes where the role is enabled. The guide states that deduplication "is applied only to NTFS/ReFS volumes on which the Data Deduplication role is enabled," and that the General-purpose file server usage type applies default policies for typical data shares. It further specifies the file size limits: "Files smaller than 32 KB are not deduplicated; supported files are 32 KB up to multiple terabytes," and clarifies that optimization jobs process eligible files during scheduled runs.
Applying those rules:
* Volume D has Data Deduplication enabled (General-purpose). After moving File1 (500 KB) from C: to D:, it resides on a deduplicated volume and exceeds the minimum size threshold, so it will be deduplicated by the next optimization job.
* File3 (1 MB) is moved off the deduplicated volume (to E:), and dedup only affects enabled volumes; therefore it will not be deduplicated.
* File4 is a copy of File2 (10 KB) on D:. Because the file is smaller than the 32-KB minimum, it is not deduplicated even though it is on a deduplicated volume.
Thus the correct outcomes are YES for File1, NO for File3, and NO for File4.
